I use a 12V battery to power the trolling motor for my kayak. I decided to buy the Infinitum Desulfator to salvage a 3-year old sealed lead acid battery which was completely "dead". To my surprise, the battery came back to life!

Testimonial update: We managed to get an update from Gerald from the last time he left a testimonial with us in June 6th, 2009. His purchase was made on February 27th, 2009. Here is what he had to say about his experience since then:

"I've never had another dead battery during usage since I purchased your desulfators! I use your desulfators every time I charge my trolling motor batteries. I'm getting up to four years of service life on my batteries now."
